1. Modal domains and selectivity in large square lasers
Modes in square resonators have C4v symmetry. A special set of modes in these resonators have odd parities and behave like whispering gallery modes. These quasi-whispering gallery modes have high quality factors and exhibit interesting features. In particular, higher order quasi-whispering gallery modes present nodes that seem to be grouped into smaller doma

2. Ressonadores de microdiscos com região ativa nanoestruturada bombeados por injeção eletrônica / Microdisk resonators with nanostructured active region pumped by electronic injection
This doctorate¿s thesis presents the growth of InAs quantum dots directly on high bandgap InGaAsP (?g=1420 nm) barriers to be used as the active region of microdisk resonators with emission in the C-band (1520¿1570 nm). Based on photoluminescence and atomic force microscopy experiments, the occurrence of inter-diffusion on the InAs/InGaAsP interface is cal

3. InstrumentaÃÃo para espectroscopia de modos Ãpticos com alto fator de qualidade em microesferas de sÃlica
Neste trabalho, realizou-se a instrumentaÃÃo eletrÃnica de um laser de diodo sintonizÃvel com cavidade estendida para espectroscopia no visÃvel dos automodos de microesferas de sÃlica. Para isto, à desejÃvel desenvolver uma fonte de luz sintonizÃvel por alguns GHz, apresentando uma largura de linha mÃxima de 1 MHz, jà que o intervalo espectral liv

4. Synthesis and characterisation of CdS nanoparticles in mesoporous copolymer template
Micron-sized spheres of mesoporous styrene-divinylbenzene (Sty-DVB) copolymer were produced by suspension polymerisation in the presence of inert diluents. Using these mesoporous microspheres as a template, optically stable CdS nanoparticles have been synthesized. To characterize these CdS nanoparticles, Raman spectroscopy and micro-photoluminescence were us
